If not asbestos as you mentioned it could be mineral wool which is made up of crushed rock and certain fireproofing chemicals or a cellulose( Shredded newspaper) product which also has fire proofing and mold/mildew resistant chemicals in it as well as a glue similar to Elmer school glue. These products are sprayed on wet( glue & water) and act as a sound and or R rated insulation product. These are usually spray painted as a roller would end up removing a lot of the product.
